MUSIC-DESK FOB PIANOS.

Specification of Letters Patent.

Patented June 23, 1914.

Application filed. October 3, 1913. Serial No. 793,219.

To all whom it may concern Be it known that I, ALB1N WILBERG, a citizenof the United States, residing at De Kalb, in the county of Dekalb andState of Illinois, have invented new and useful Improvements inMusic-Desks for Pianos, of which the following is a specification.

The invention relates to pianos, and more particularly to casingstherefor, and has for an object to provide a music supporting desk ormember for the casing.

The invention embodies, among other features, the provision of aswinging front section arranged and constructed so as not to rattle, andwhich can be readily swung into open or closed position relatively tothe casing, the said swinging front section being furthermore adapted toconstitute a supporting rack for music and the like.

The invention further embodies the provision of a swinging front sectionmore particularly known as a music desk for use on upright pianos andwhich can be readily swung into an open position relatively to thecasing and held in this position or as easily swung into closed positionon the casing, with means for accomplishing this result.

In the further disclosure of the invention reference is to be had to theaccompanying drawings, constituting a part of this specification, inwhich similar characters of reference denote corresponding parts in allthe views, and in which:

Figure 1 is a vertical sectional view taken through the piano casing,showing the swinging section in closed position; Fig. 2 is a similarview showing the swinging section in open position; Fig. 3 is afragmentary vertical sectional view showing the manner of swinginglysupporting the section on the casing; Fig. 4 is a vertical sectionalview taken on the line 44 in Fig. 1; and Fig. 5 is a horizontalsectional view taken on the line 55 in Fig. 3.

Referring more particularly to the views, I provide a piano casing 10having an opening 11 in the front 12 thereof and adapted to be closed bya front section 13 having swinging engagement with the casing 10, thisbeing accomplished through the medium of a plurality of hangers 14secured to the front section 13 and preferably of a hook-like nature,with the hook portions of the hangers journaled on headed screw bolts 15carried on the piano casing 10. In order to prevent any rattling of thefront section relatively to the piano casing and particularly at thepoint of pivotal connection of the front section with the casing, a flatleaf spring 16 is interposed between the hangers and the screw bolts asshown.

The lower end of the front section 13 carries a shelf 17 adapted tosupport music, lying against the front section and secured to the rearface of the front section 13 is a U-shaped supporting member 18 havingeccentrically mounted to swing thereon a bar 19 provided with alongitudinal slot 20 terminating at an opening 21 and also including arecess 22. Screws 23 are provided to secure the bearing member 18 to theback of the front section 13 and the said screws also carry and supporta spring-like locking member 24 between the supporting member 18 and thefront section 13. The bar 19 carries a lateral pin 25 adapted to engagethe locking member 24 and operate over the same, the said locking memberbeing provided with an upper recess 26 and a lower recess 27, into whichthe pin 25 is adapted to be received when the front section is in closedand open positions respectively. A transverse pin 28 is carried by thecasing 10 and passes through the slot 20 of the bar 19, as shown.

In order to cushion the front section 13 when it is swung from open intoclosed position a stop member 29 including a felt cushion 30 ispreferably secured to the casing 10 and the cushion thereof adapted tobe engaged by the section when the same is moved into closed positionrelatively to the casing.

When the front section 13 is in closed positiointhe bar 19 will lie insubstantially a vertical position, with the pin 25 of the plate reposing in the upper recess 26. When an upward pull is exerted on thefront section the bar 19 will swing on its point of pivotal connectionwith the supporting member 18, thus causing the pin 25 to be removedfrom the upper recess 26 and, as the front section is swung outwardly,the bar swinging upwardly and forwardly, will cause the pin 28 to lie inthe recess 22, the pin 25 of the bar when the front section has beenswung into its outermost position, being adapted to spring into therecess 27, thus with the cooperation of the spring-like locking memberholding the front section in open position relatively to the front ofthe piano casing. hen it is desired to return the front section toclosed position it is only necessary to exert a backward pressure uponthe face of the front section, thus causing the pin 25 to spring out ofthe recess 27 and causing the rear end of the plate 19 to gravitate intothe position shown in Fig: 1 so that the pin 25 will be again receivedin the upper recess 26 as is also shown in Fig. 1.

From the foregoing description it will be apparent that my device is ofa simple construction, can be readily used in connection with pianos andother similar musical instruments and will efi'ectively perform the workfor which it is intended.

Having thus described my invention, I claim:

1. A music desk for pianos, comprising a front section having swingingconnection with the front of the piano casing, a bar having pivotalconnection with the front section and a sliding connection with thecasing, a locking member on the front section, and means carried withthe bar and movable over the locking member for holdingthe front sectionrelatively to the said casing.

2. A music desk for pianos, comprising a front section having swingingconnection with the front of the piano casing, a bar having pivotalconnection with the front section and a sliding connection with thecasing, a locking member on the front section, and a pin carried withthe bar and movable over the locking member for holding the frontsection relatively to the said casing.

3. A music desk for pianos, comprising a front section having swingingconnection with the piano casing at its upper end, a supporting membercarried by the front section, a bar mounted to swing on the supportingmember and having sliding connection with the casing, a locking membercarried by the front section adjacent the supporting member, and a pinextending laterally from the bar to operate over the locking member andlie in a recess therein to lock the front section relatively to thecasing.

l. A music desk for pianos, comprising a front section having swingingconnection with the piano casing, a longitudinally slot ted bar, abearing member carried by the front section and having thelongitudinally slotted bar mounted to swing thereon, a pin carried bythe casing and operable in the slot of the said bar, a locking member onthe front section, and means carried by the bar and adapted to engagethe locking member for holding the front section relatively to thecasing.

5. A music desk for pianos, comprising a front section having swingingconnection with the piano casing, a longitudinally slotted bar, asupporting member carried by the front section and having thelongitudinally slotted bar mounted to swing thereon, a pin carried bythe casing and operable in the slot of the said bar, a spring-likelocking member on the front section, and a pin carried by the bar andadapted to engage the locking member for holding the front sectionrelatively to the casing.

In testimony whereof I afIiX my signature in presence of two witnesses.
